Here's a few links with helpful information on liver shunts.
Hope everything turns out okay.
University of TN does a lot of work with liver shunt dogs.
Doctor Tobias is very well respected for her work with shunt dogs.
The surgery has an excellent success rate.
Also there is a Yahoo forum with a nice Liver Shunt support group...
you might want to look to them for advise.
Best Wishes, Kara
